GOODS-DETACHING DEVICE IN ENDLESS-ROPE TRANSPORT APPLIANCES.

SPECIFICATION forming part of Letters Patent No. 788,543, dated May 2, 1905.

Application iilnri September 29, 1904. Serial Nol 226.59l.

To all whom t may concern:

Be it known that I, GEORG LEUE, a citizen of the Empire of Germany, and a resident of Berlin, Germany, (whose post-oflice address is Kurfrstendamm 24,) have invented certain new and useful Improvements in Goods-Detaching Devices in Endless -Rope Transport Appliances, of which the following is a specilicatiou The subject of my invention is a devicefor automatically detaching and lowering the goods from endless-rope transport appliances, more especially those the points oi' suspension ofthe rope of which are movable, as is, for instance, the case in coaling apparatus for ships at sea.

My invention'is illustrated in the accompan ying drawings, which show one form of construction of the device as employed for coaling ships at sea-an endless transport-rope eX- tending from the eoaling-steamer to the warship in tow and running over pulleys secured to the masts of the two vessels.

Figure l is an elevation showing the improved apparatus and the adjacent portion of the endless-rope transport appliance. Fig. 2 is a side elevation seen from 'the left-hand side of Fig. l, and 3 is a plan of same. Fig. 4 is a detail view, drawn to a longer scale, showing the means employed for connecting the delivery rail and wire. Fig. 5 is an edge view, and Fig. 6 a front view, of the goodscarrying hook, both being likewise drawn to a longer scale.

a is the endless transport-rope, which runs in the direction of the arrow on the grooved pulley the shaft of which is mounted in two plates c, carried by a bolt d. rlhe ends of the latter turn in bearings a in the collars f, which embrace the mast .fr of the war-ship. Owing to this arrangement, the rope despite transverse movements of ship always remains in the plane of transport.

rlhe rope a transports the sacks of coal uninterruptedly, the said sacks being hung on the rope in well-known manner by means of a double hook. For the sake of better understanding of the invention one of these double hooks is shown in Figs. 5 and 6. It consists of a safety-hook g, pivoted to a shank 7i, a

bi'll c', forming a large slide-hook, and asmall hook c for engaging the transport-rope. The hook /r is pivoted to the shank /t in such manner that it can be turned back to release the rope immediately. A round pin Z, having` a larger rectangular end and sliding in the shank t, is pressed in against the action of the spring m so that the thinner round portion of the pin comes behind the hook In, thus allowing the latter space to pass by on being raised.

Immediately the sacks reach the end of the rope-that is to say, arrive at the mast .fa-*they are removed automatically from the transportrope and are transferred to a downwardly and laterally inclined delivery-wire, on which they slide down to the deck ofthe man-of-war. For this purpose an elbow-shaped arm a is loosely mounted on the shaft of the grooved pulley and to the top part of this arm is secured a roller e, restingon the rope a, so that the arm a shares all the vertical movements of the rope a. The arm n. is provided with a stop o for the pin Z ot' the hook zto strike against. The arm also has cross bars p, into which are screwed bolts q, carrying the delivery-rail 9. rl`he latter consists of a somewhat ascending part i", located close to the rope a, and descending part r2, running away from the rope.

The delivery-wire s is not rigidly connected with the bottom end of the rail 7', since the latter must follow the movements of the grooved pulley t caused by the motion of the ship and must always occupy the same position relatively to the transport-rope. For this purpose in the bottom end of the rail r is provided the socket t of a ball-joint, Eig. 4, in which socket a ball-head a, secured to a tube o, can freely turn. In the other end of the tube o there slides freely the upper end ofthe delivery-wire s. The latter turns on the horizontal pin 1.o,passing through the lower part of an arm z which is rigidly secured to the mast ai, said lower part turning on a pin fw in the upper part of the arm y.

The operation ot' the apparatus is as follows: The sack of coals on the eoaling-steamer is hung by hand or automatically, by means of the hook r, on the continuously-traveling endless rope a, which transports the sack to the IOO war-ship. Immediately the hook reaches the top end r' of the rail the large hook t' will slide up the latter. At the hig'hest point of the rail fr the pin lof the hook will strike the stop 0 and will be pushed in in such manner that it releases the hook is, which now swings up so that the rope c is released. The hook z', with the sack, now slides down the part r2 of the rail and over the tubular extension o on the wire .5' and thence to the deck, where the sack can be released from the hook. The empty sack, with hook, is then rehung on the other half of the rope c, whereby it is returned to the coaling-steamer.

In the herein-described apparatus the detachment of the goods from the transportrope and the delivery of the same upon the deck goes on automatically without interruption and without any reference to the alteration of direction of the ship. This is due to the connection of the rope s to the rail r by means of the ball-and-socket joint tu and the telescopic tube@ and, further, to the universal joint at w w, whereby the wire is rendered whlolly independent of the movements of the rai It will be understood that the constructional details of the apparatus may be greatly varied and the elements herein described replaced by equivalent parts Without departure from the essential features of the invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a transport appliance for conveying loads in horizontal direction, in combination, an endless rope, a grooved pulley at the delivery end of the same, a horizontally-swinging arm secured to a suitable support and carrying the pulley, an arm carried by the pulley-shaft and having a roller resting on the endless rope, avertically-adjustable, descending rail carried by the arm and laterally deviating from the rope, and a descending wire connected with the lower end of the rail by a universal joint, substantially as described.

2. In a transport appliance for conveying loads in horizontal direction, in combination, an endless rope, a grooved pulley at the delivery end of the same, a horizontally-swinging arm secured to a suitable support and car-v rying the pulley, a descending rail located in the vicinity of the rope from which it laterally deviates, a suitably-supported descending wire, a tube receiving the upper end of the wire, and a universal joint connecting the said tube to the bottom end of the rail, substantially as described.

3. In a transport appliance for conveying loads in horizontal direction, in combination an endless rope, a grooved pulley at the delivery end of the same, a horizontally-swinging arm secured to a suitable support and carrying the pulley, an arm carried by the pulley-shaft and having a roller resting on the endless rope, a vertically-adjustable, descending rail carried by the arm and laterally deviating from the rope and a descending wire connected with the lower end of the rail by a universal joint and a universal-joint device connecting the wire to a suitable support, substantially as described.

In testimony whereof I aiiix my signature in presence oi' two witnesses.

GEORG LEUE.
